Guys, even if you get no interview calls tomorrow relax.
I think that tomorrow is Gandhi Jayanti so most probably no calls would be rolled out tomorrow.
And according to the mail, you would be notified only 5-7 days prior to the interview.
So you can even expect the calls to be rolled out by next week,
Please do not make any assumptions on your own. And keep checking your portal.
Even if you do not get the mail, I think they might update your status as this happened last year as well.
